Application filed February 15, 1906. Serial No. 301,256.

To aZZ whom it may concern:

Be it known that I, ALBERT J. REED, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wire Mattresses, of which the following is a specification.

The object of my invention is to provide a spring-wire mattress of simple and economical'construction which will retain its form and the relative relations of its parts under pressure, thus affording a uniform surface at all times.

The class of mattresses to which this improvement relates are composed of a series of conical sprin s arranged in parallel rows and retained in t eir proper position by tie and key rods, the ends of which are secured to a border-frame surrounding the springs. The main objection to such a mattress is that the springs slip from their proper position under pressure,which results in a uneven and weak surface. I overcome this objection by constructing the tie-rods with loops having abrupt and substantially parallel sides engaging the border-frame and springs, so that when the key-rods are set the top coils of springs and border-frame are firmly held within the loops and a longitudinal movement of the springs relative to the key-rods and border-frame is prevented, thereby always securing a uniform surface.

In the drawings, Figure 1 is a plan view of a corner of a mattress. Fig. 2 is a transverse section on the line 2 2 of Fig. 1, and Fig. 3 is a fragmentary edge view of the upper lefthand corner of Fig. 1 looking in the direction of the arrow.

3 represents a border-frame of the usual type inclosing a series of springs 4, which are arranged in parallel rows and connected to the frame and to each other by the tie-rods 6 and 7 and the key-rods 8 in the following manner.

A tie-rod-say 6connects each row of springs, one end of it being secured to the border-frame in any of the well-known ways and then run parallel to said frame until it meets the under side of the top coil of a spring at 9, when it is bent abruptly vertical, (10,) passed over the top of the spring, and then bent abruptly down (11) to a point slightly lower than the bend at 10, forrrnng the loop 12 with substantially parallel sides on either side of said top coil. It is then bent at an angle (13) to meet the borderframe or a spring, if it is not an outside tierod, where it is again bent vertically, (14,) passing over the frame, forming a loop 15, similar to 12, with the parallel sides, when it returns in the same manner at an opposite angle 16 to the angle 13 over the frame and spring under the top coil and continues parallel to the border-frame (shown at 17) until it meets the next spring, when the same construction is repeated on all the springs and the tie-rod is secured at its other end to the frame. It will be thus readily seen that in its return movement from the outside shoulder of the loop 15 anose or loop 18is formed which is slightly shorter than the bellied portion between the two inner shoulders, as shown at 13, Fig. 2, so that when the key-rod 8 is secured to the nose in any of the well-known ways, as shown at 19, and passed under the borderframe and top coil of the spring both of the latter are firmly held within the loops. (Shown at 20 and 21.) This construction permits all the tie and key rods to be constructed alike, as the intermediate springs are secured to each other in the same manner as the end springs of each row are secured to the borderframe.

Only two rows of two springs each are shown in the drawings but the method of connecting the springs is uniform throughout, except as to the tie-rod at the opposite end from the tie-rod 6, which must necessarily be reversed to be connected to the frame.

I am aware that there are various constructions employing tie and key rods to retain the springs in position; but I believe myself to be the first to provide loops with abrupt shoulders on both sides of the border-frame and springs with the nose 18 in a plane slightly above the bellied portions 13 and 16 between the two inner shoulders, so that the frame and springs are ositively locked within the loops and a disp acement of the springs prevented.

Having described my invention, what I claim, and wish to secure by Letters Patent, 1s

In a wire mattress the combination of a series of springs arranged in parallel rows, a border-frame surrounding said springs, tierods connecting said springs to the borderframe and to each other, the ends of said rods being attached to the frame and having intermediate portions passing under the top coil of a spring and bent to form substantially vertical and parallel shoulders on both sides of said coil and frame, a downwardlysaid shoulders whereby a longitudinal moveprojecting nose formed by two of the bent ment of said springs relative to said key-rods IO shoulders, the end of which is slightly above is prevented. the bellied portions between the inner adjacent shoulders, and key-rods secured to and passing through the noses formed in said tie- Witnesses: rods and adapted to confine the top coils of OTTO SoHMoLL, said springs and said border-frame between LOUIS J. NOWLAN.
